Theoretical Model of the Thermocline in a Freshwater Basin
Publisher: American Meteorological Society
Abstract: Two striking empirical facts represent a starting point of the discussion: (i) vertical temperature profile in a thermocline, a region of supercritical stability adjoining a mixed layer, proves to be self-similar in a ...
Closure Schemes for Stably Stratified Atmospheric Flows without Turbulence Cutoff
Publisher: American Meteorological Society
Abstract: wo recently proposed turbulence closure schemes are compared against the conventional Mellor?Yamada (MY) model for stably stratified atmospheric flows. The Energy- and Flux-Budget (EFB) approach solves the budgets of ...
Revisiting the Turbulent Prandtl Number in an Idealized Atmospheric Surface Layer
Publisher: American Meteorological Society
Abstract: ospectral budgets are used to link the kinetic and potential energy distributions of turbulent eddies, as measured by their spectra, to macroscopic relations between the turbulent Prandtl number (Prt) and atmospheric ...
A Total Turbulent Energy Closure Model for Neutrally and Stably Stratified Atmospheric Boundary Layers
Publisher: American Meteorological Society
Abstract: This paper presents a turbulence closure for neutral and stratified atmospheric conditions. The closure is based on the concept of the total turbulent energy. The total turbulent energy is the sum of the turbulent kinetic ...
